Beta Function Constraints from Renormalization Groups Flows in Spin Systems
Joao D. Correia
Inspired by previous work on the constraints that duality imposes on beta functions of spin models, we propose a consistency condition between those functions and RG flows at diffe…

A Note on the Barrier in Liouville Theory
João D. Correia
The instability of Liouville theory coupled to matter fields is shown to persist even when the ``spikes'' which represent highly singular geometries are allowed to interact i…
